Chiral superfluidity with p-wave symmetry from an interacting s-wave atomic Fermi gas.
Chiral p-wave superfluids are fascinating topological quantum states of matter that have been found in the liquid (3)He-A phase and arguably in the electronic Sr2RuO4 superconductor. They are fundamentally related to the fractional 5/2 quantum Hall state, which supports fractional exotic excitations. Past studies show that they require spin-triplet pairing of fermions by p-wave interaction. Her...
متن کاملInduced P-wave superfluidity in asymmetric fermi gases.
We show that two new intraspecies P-wave superfluid phases appear in two-component asymmetric Fermi systems with short-range S-wave interactions. In the BEC limit, phonons of the molecular BEC induce P-wave superfluidity in the excess fermions. In the BCS limit, density fluctuations induce P-wave superfluidity in both the majority and the minority species. These phases may be realized in experi...
متن کاملSuperfluidity and magnetism in multicomponent ultracold fermions.
We study the interplay between superfluidity and magnetism in a multicomponent gas of ultracold fermions. Ward-Takahashi identities constrain possible mean-field states describing order parameters for both pairing and magnetization. The structure of global phase diagrams arises from competition among these states as functions of anisotropies in chemical potential, density, or interactions. They...

متن کاملOn Quartet Superfluidity of Fermionic Atomic Gas
The superfluidity is so far known to be sustained by the Bose-Einstein condensate or the Cooper-pair condensate. The former is realized in liquid He and some atomic gas of an alkali element, while the latter is realized in liquid He and a variety of superconductors. Recently, it has been found that Cooper pairs are formed in the fermionic atomic gas of alkali element and the crossover to the Bo...
